Method of assembling an armature to a solid pusher, and the resulting assembly

摘要

The invention relates to a method of assembling an armature ( 3 ) to a solid pusher ( 1 ) extending through an opening ( 4 ) in the armature ( 3 ), the method comprising the steps of: making at least one groove ( 2 ) in the pusher ( 1 ); then inserting the pusher ( 1 ) into the opening ( 4 ) in the armature ( 3 ) so that the groove ( 2 ) extends substantially adjacent to a face of the armature ( 3 ), and interposing between the pusher ( 1 ) and the armature ( 3 ) a ring ( 5 ) that projects on either side of the armature ( 3 ) and that overlies the groove ( 2 ); and then crimping the ring ( 5 ) on either side of the armature ( 3 ) while holding the armature ( 3 ) perpendicular to the pusher ( 1 ).
